I'm new to Arduino. I started out with a Japanino and then quickly got hooked and got a Seeduino and Rainbowduino.
Unfortunately, I feel very guilty about buying these non-Italian boards, even if I felt they were better in various ways than the current Diecimillinova, which I can't even spell. 
Anyway, to assuage my guilt, I bought Massimo's book. But I'd really also like to donate some money to the Arduino.cc project. I looked on the home page and couldn't find a "donate money" button anywhere.
Is hardware sales the only way Arduino makes money? Why not add a donate button?
